The Beverage group × FSW interaction was a significant predictor of the CE in RT, β = −.24, t(83) = −2.17, p = .03. For the placebo group, FSW amplitude was a significant predictor of the size of the CE in RT, β = −.37, t(29) = −2.11, p = .04. This was not the case for the control or alcohol groups, β = −.02, t < 1, p = .94 and β = .01, t < 1, p = .96, respectively (see Figure 5B). The full model explained a marginally significant proportion of variance in the CE, R2 = .06, F(2, 83) = 2.78, p = .06.
